i j eas HEATING strovns.

My invention relates to improvements in` gas heating stoves.

One or the objects oi my invention is `to provide a gas heating stove so arranged so as to permit o l a more even distribution oiE the heat rays throughout the space to be heated; a more particular object in this con'- nection being to provide an arrangement in which the heat elements are arranged in a curvilinear series extending partially about the stove, with the space in lront o the heat elements `l'ree from obstructions,` so that the rays of heat are radiated in radial 'planes extending;` from the sides oi the stove as well as the front` thereof; a further object in, this connection being" to arrange the heat elements that the elements at each end ot the series ol elements are located on the are oil' a circle of smaller radius than that ol the intermediate elements, so that the propel' amount of heating area may be secured withj out unduly extending the heating elements forwardly, would be necessary iii the heat elements were arranged. on a true circle, and at the saine time imparting to the front o'it the stove a flattened appearance.

Fig. 5 is a detailed plan view ol the burner, mixing chamber and mixing valve.

Re'erring to the drawings, 1` represents the base of the stove oli curved lorin. The rear edges of this base are connected to vcr- Vtical standards 2 and the forward portion of the base is provided with a pair of supportingr legs 3. `Secured to the base 1 and by the standards, is a support for the heatH ing` elements. This support consists et a curved portion 5, coneavo-convex in cross section, an inner projecting shelf 6, an intere mediate shelfI 7 and. a rear cross bar 8. :intermediate shelf forms a support` for a i oit' heat ants 9, Wh are lmown Application filed February 17, 1926. Serial No. 88,753.

port for a curved bach wall 10 of lire-proof material.` This back wall 10 has at its upper end an integrally formed overhanging portion 10', the forward edge of which 1s of curved form. The radiants 9 are formed of lire-proof material and are of a type well. known in theart of lEras heating stoves. rlhese radiante are heldlin position by a flange 5 formed atthe juncture olf the portion 5 and shelf 7 and also by a groove formed on 'the under side of the portion 10, as indicated in dotted lines 10. The lireback 10`is held in position by forming; therein grooves 11, which grooves engage-the ianer projecting edges of the standards 2 as shown in Fig. As clearly shown in Fics 3 and 1- a jacket plate 20 oit usual toi-1n. is secured to the rear faces of the uprights 2, and by reason of the particular connection of `the ends of the substantially semi-cylink drical lire-back 10, no portion of the lireback contacts with the jacket plate, the space between the lire-bach: 10 and jacket plate 20 providing for circulation of air therebetween so the stove may be set close to a house wall without danger ol setting lire to the saine due to? the heat radiatingl iroin` the fire-back, when the stove is in use. A cap oil ornamental appearance laid on the over-hangin5 1,V portion 10 olr the fire wall, the upper end oi the jacket plate 2.0, and on the upperends olf the standards. rlhe curves upon which the support, back wall and over-hanging portion are formed are such that the radiante at each end. of the series are located on the are oi a circle ol. smaller radius Athan that of the intermediate radiants. i

The burner which I employ consists of a curved forwardly disposed chamber 12, a rear chamber 13, two hollow arms 111- conneeting` the two chambers, a hollow 1nember 15 connected at its rear end with the cl'lamber 13, and a fuel. and air mixing `valve 1G connected `with the forward end et' the member 15. The chambers 12 and 13 and the arms 1d are jnefierably integrally iliormcd while the member 15 is bolted to the flanged ope] het oni. oit the chamber The burner tluifl, 4l is maneiland witlzi ea Elfi", pro

jecting from the rear edge of the shelf 6, and is also fastened to the standards 2 and y to the bosses formed on its rear side of the cross-bar 8. The chamber 12 is disposed beneath the radiants 9 and is provided with a series of nozzles 18, one for each radiant, which are screwed into openings 18 in the upper wall of the chamber 12. It will be noted that the passage in the member 15 diverges toward the mixing chamber, while the passages in the members 1,4 converged from the chamber 13 to the chamber 12. This allows the air and the gas to enter the mixing chamber in an expanded condition to secure a more thorough mixture, and to be then again contracted before enteringthe burner chamber 12 to give it the proper density for veliicient combustion.

By the construction desc `ibed it will be seen that I have provided a heating stove which, upon being placed in a fire place or near one wall of a room, will radiate the' rays of heat in all directions in the room, thus maintaining more nearly a uniform temperature in all parts of the Vroom than can be obtained by the usual type of gas heating stoves. It will be noticed that the frame or supporting members of the stove are so arranged that there will be no obstructing parts in front of the radiants, particularly those radiants at the extreme ends of the series, so that there will be no interference with the radiation of the heat rays "from one end of the series of radiants to the other. The disposition of the end radiants on short arcseand the intermediate radiants on`aJ comparatively long arc also provides an arrangement which has adequate heating surface without unduly extending 'the heating surface forwardly, as would necessarily be the case if the radiants were arranged on a true circle, and this arrangement also gives -a more flattened or straight effect to the forward portions of the heating surface.

,Having thus described my invention, I claim: Y Y i l. In a gas heating stove, a supporting Y frame open at the front, and a series 0f eX- posed heat elements arranged in the open front of said stove in a curvilinear series, so as to extend across the front and about part at least of the sides of said stove, the elements at each end of the series of elements being arranged on the arc of a circle of shorter radius than that of the intermediate elements.

2. In a gas heating stove, an open front .support-mg frame, a curved fire back supported by said frame, and a series of exposed heating elements arranged in a curved line in front of said back, so as to extend only across the front and at least part of the sides of the stove, the elements at each end of the series of elements being arranged on the arc of a circle of shorter radius than that of the intermediate elements.

3. In a gas heating stove, a supporting frame open at the front including a perpendicular standard at each side of the rear thereof, a series of exposed heating elements arranged in the open front of said stove in a curvilinear series so as to extend across the front and about part at least of the sides of said stove, the elements at each end of the series of elements being arranged on the are of a circle of shorter radius than that of the intermediate elements, all of said elements being arranged in vertical planes forward of the vertical planes of the front faces of said standards.

4. In a gas heating stove, a supporting base, uprights at the rear corners of the base, said uprights having at their faces inwardly projecting flanges;` a jacket plate connecting the rear faces of the uprights; a lire-back supported on said base in front of the jacket plate, each end of said lire-back having a. groove receiving the llange of its adjacent upright whereby the lire-back is entirely spaced from the jacket plate; and a series of heating elements mounted in the outer face of the fire-back.

5. In a gas heating stove, a supportingr base, uprights at the rear corners of the base, said uprights being of substantially channeled cross-section with the bosoms of the channels opening inwardly; a jacket plate connecting the rear legs of the channels; a fire-back supported on said base in front of the jacket plate, each end of said lireback having a groove receiving the end of the outer leg of its adjacent channel whereby the fire-back is entirely spaced from the jacket plate; and a series of heating ele ments mounted in the outer face of the fireback.

6. In a gas heating stove, a substantially semi-circular supporting base, uprights at the rear corners of the base, said uprights having at their outer faces inwardly projecting flanges; a jacket plate connecting the rear faces of the uprights; a substantially semi-cylindrical lire-back supported on said base in front of the jacket plate, each end of said fire-back having a groove receiving the flange of its adjacent upright whereby the fire-back is entirely spaced from the jacket plate to foiin an air space therebetween; a series of heating elements mounted in the outer face of the fire-back; and a cap s ated upon the upper ends of the fire-back, uprights, and jacket plate.

V7. In a gas heating stove, a substantially semi-circular supporting base, uprights at the rea-r corners of the base, said uprights being of substantially channeled cross-*section with the bosoms of the channels opening inwardly; a jacket plate connecting the rear legs of the channels; a substantially semicylindrical fire-back supported on said base in front of the jacket plate, each end of said {ire-back having a groove receiving the end of the outer leg of its adjacent Channel whereby the fire-back is entirely spaced from the jacket plate to form an air space therebetween; a series of heating elements mounted in the outer face of the fire-back; and a cap seated upon the upper ends of the hre-baek, uprights and jacket plate.

In testimony whereof, I have hereunto set my hand this 15th day of February, 1926.
